Carotenoid Mutants of Mucor circinelloides
Botanica Acta, 1995AbstractThe wild‐type of the filamentous fungus Mucor circinelloides accumulates the yellow pigment β‐carotene. At a continuous blue‐light fluence rate of 0.1 W/m2 the β‐carotene content increases about eight fold over the dark controls. Among the mutants isolated after exposure of spores to either N‐methyl‐N'‐nitro‐N‐nitrosoguanidine or ICR‐170, a red

Metabolic engineering of Mucor circinelloides to improve astaxanthin production
World Journal of Microbiology and BiotechnologyAstaxanthin is a bioactive natural pigment with antioxidant properties. It has extensive applications within the industrial sector as well as in human and animal health. Mucor circinelloides is a zygomycete fungus that accumulates β-carotene as the main carotenoid compound. M.

Activation of Mucor circinelloides lipase in organic medium
Journal of Molecular Catalysis B: Enzymatic, 2002Abstract An intracellular Mucor circinelloides lipase either in the form of mycelium-bound enzyme, or in the homogeneous and soluble form, was subjected to activation experiments. It was found that some compounds, such as pyridine, diethanolamine (DEtA), triethanolamine (TEtA), and cetylpyridinium bromide, either increase or decrease the synthetic ...

Transformation of Mucor circinelloides f. lusitanicus Protoplasts
2014Since the first report of a Mucor circinelloides transformation system, many things have been improved by small changes that either simplify the original procedure, or use new technologies. Today, people working on this fungus have alternative methods of transformation that allow them choosing the most suitable one for their purposes.

Mucor circinelloides a destructive hyperparasite of Rhizopus nigricans
Mycopathologia, 1978In vitro studies on hyphal interactions between phyllosphere and phylloplane fungi revealed Mucor circinelloides to be a destructive hyperparasite of Rhizopus nigricans. The mycoparasite penetrated the host hypha and formed sporangiophores and sporangia on different parts of Rhizopus nigricans.

Effect of Acetate and pH on Sunflower Oil Assimilation by Mucor circinelloides f. circinelloides
Systematic and Applied Microbiology, 1999Summary Mucor circinelloides f. circinelloides CBS 108.16 exhibited poor cell growth and substrate assimilation (32.5% of extracellular lipids) when grown with sunflower oil as sole carbon source. By contrast, in the presence of both sunflower oil (30 g/l) and sodium acetate (10 g/l), nearly complete utilization of both substrates (97.5% of ...

Mucor circinelloides LU M40 and Penicillium aurantiogriseum P 35 produce extracellular beta-glycosidases that are active on the cyanogenic glycoside amygdalin. From the culture broths of M. circinelloides, only one beta-glycosidase could be identified, while two different enzymes - both having amygdalase activity - were found in culture broths of P ...

Characterization of a leuA gene and an ARS element from Mucor circinelloides
Gene, 1989A 4.4-kb PstI restriction endonuclease fragment of Mucor circinelloides DNA has previously been shown to both complement a leuA- mutation, and to enable the autonomous replication of plasmids within this organism. The complete nucleotide (nt) sequence of this fragment has been determined and an open reading frame of 1935 bp with no introns has been ...

Critical applications of Mucor circinelloides within a biorefinery context
Critical Reviews in Biotechnology, 2019The establishment of an efficient and feasible biorefinery model depends on, among other factors, particularly the selection of the most appropriate microorganism. Mucor circinelloides is a dimorphic fungus species able to produce a wide variety of hydrolytic enzymes, lipids prone to biodiesel production, carotenoids, ethanol, and biomass with ...
